Powers: The
Invaders could turn invisible, were armed with rayguns and used a spaceship
capable of interplanetary travel.

History: (Plastic
Man (Quality) #35) – The Invisible Invaders were Saturnians sent to Earth to study
it before an invasion. They landed in Corn Flats and used their ability to turn
invisible to keep anyone from investigating their doings. They stole a number of
objects from citizens before Plastic Man and Woozy Winks were called in to check
out their ship. They tried to kidnap Woozy and others because they needed to
study humanity, but Plas boarded their ship and forced them to flee back to
Saturn.

In the pre-Crisis DC Universe the Invaders lived on Earth-2.
The Invaders, like most characters from the golden age Plastic Man stories, may or may not be a part of post-Crisis DC continuity.

The Invaders were originally a Quality Comics character, which DC obtained the rights to in 1956.
